Here is my version of the B blouse, from the Stylish Dress Book 1. The Fabric is Jezebel by Anna Fishkin for Red Rooster Fabrics.
The making of this blouse is quite straight-forward. You just need to know that the pattern for the bottom part of the sleeves must be widened by 10cm in order to be gathered and give this bubble effect. I think it is quite a good choice for a beginner seamstress.
